TYPOGRAPHIGAL MACHINE.

Specification of Letters Patent.

Patented Mar. 3, 1914.

To all whom 'it may concern Be it known that I, JOI-IN R. Rooms, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical Machines, of which the 'following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such for instance asthe linotype machine illustrated in my previousLetters Patent No. 8118,77 1, wherein is presented a plurality of distinct distributing mechanisms, these mechanisms being two in number, one intended for the separation of the type or matrices from the -composed lines, according to font, and the others arranged to overlie a plurality of magazines and each serving to return the matrices of one 'font to their appropriate channels therein. In distributing mechanisms of this character, it is desirable and necessary that stop devices be employed, for the purpose of arresting the distributer in the event of the displacement of a matrix or other untoward circumstance, which otherwise might result in injury or breakage to the parts. In the present instance, I provide both the font and main distributers with such stop devices, and arrange them in such manner that one of them may be arrested without affecting the other. In the specilic form illustrated, the actuation of the stop devices connected to the main distributing mechanism serves to arrest both it and the font distributing mechanism, whereas the arrest of the font distributing mechanism does not similarly arrest the main distributing mechanism. This capability of independent stoppage is of considerable convenience for a number of reasons. For `instance, it permits the main `distributers to proceed with the distribution of the matrices already contained therein, notwithstanding the cessation of the font distributer, and moreover, immediately localizes and indicates the existence of the fault in the font distributer, and thus prevents the necessity of searching for it through the main distributers.

In the accompanying drawing, I have shown my invention in preferred form and by way of example, and as applied to the particular style of machine indicated, but obviously many changes and variations may partly in section, having my invention ap` plied thereto; and Fig. 2 is a longitudinal vertical section through the main driving means.

The font distributing `or separating de-` vices are or may be of the general character disclosed in my application for Letters Patent, Serial No. 640,470, filed July 25, 1911. This mechanism comprises the screws A, the bridges or selectors A1` connected to the longitudinally movable block A2, which block is formed with the laterally extending piece A, having the projecting pin A4, whereby the lever arm A5 is normally supported in order to engage the clutch member A7 with the actuating clutch member A8. When the matrix X becomes jammed or is otherwise 1mproperly placed, but is still engaged by a screw A, or even if disengaged becomes an obstacle in the path ot' the other matrices, which are beiner advanced in the regular way, the block 2 and piece A3 are longitudinally shifted thereby, and the pin A4 is caused to pass from under the lever arm A5, all as indicated by dotted lines. The release of the arm A5 permits the spring A to withdraw the clutch member A7 from the clutch member AB, and thus to arrest the operation of the font distributor.

The main distributing mechanisms, designed to return the matrices X to their proper magazine channels after they have been separated according to font, comprise a plurality of distributer bars or rails B, and of conveying screws C arranged to coperate therewith in the usual manner. As the matrices drop from the rails B, they pass between the partition plates D into their channels. The edges of the plates D are movable at one side thereof, where they engage the longitudinally movable slide D1, in substantially the manner set forth in my application for Letters Patent, No. 640,009, filed July 22, 1911. Also, as in said application, the several bars D1 are arranged to impinge at their ends against a common transverse rocking frame E, to which is connected the upwardly projecting arm or pawl E1,where on the stop arm E2 normally rests. In the event of a matrix becoming displaced or jammed, or itsfailing to clear the distributer screws C, or itsbeing left in such position as to offer an obstacle to the advance of the other matrices, the continued movement of the screws, or of a matrix advanced thereby, causes the offending matrix to impinge against one of the movable partition plates D, which in turn, by reason of its engagement with the corresponding slide D1, forces the latter outwardly and thus shifts the transverse frame E and removes its upwardly projecting arm E1 from under the stop arm E2. When the stop arm E2 is thus released, it drops forwardly by gravity or otherwise and projectsits stop finger E3 into the patn of the side cam E4, with the result that the continued rotation of the cam E1 shifts the Vconnected parts laterally and breaks the driving connection, all in the usual manner. Y The several distributing mechanisms are operated from a common source of power, in the present instance, the band wheel F, which imparts motion to the friction member F2 upon the sleeve F1, the parts being normally held in their operative position by the spring F3. Mounted upon the sleeve F1 is the sprocket wheel G, from which, by sprocket gearing G1, and other gearing G2 (indicated by dotted lines), motion is imparted to the main distributer screws C. Also mounted upon the sleeve F1 is a gear H meshing into a pinion H1 on the longitudinal shaft H2, which carries the previously mentioned clutch member AS, from which motion is imparted to the font distributer. The previously mentioned cam E4 is also carried by the sleeve F1, and when the stop arm E2 is permitted to act, and due to the .engagement of its stop linger E3 with the cam, the sleeve F1 is moved laterally against the pressure of the spring F 3, and the clutching connection between the member F2 and pulley F is broken, thereby arresting the operation of both the font and main distributers. However, it will be noted that when the block A2 is moved longitudinally, so as to trip the lever arm Aand thus break the connection of the clutch members A7 and A8, the font distributer only is arrested, and the operation of the main distributing devices is not affected thereby.

As previously stated, I have shown my invention only in preferred form and by way of example, and as applied to a particular style of machine. However, many variations and modifications therein, and in its mode of application, will suggest themselves to those skilled in the art without departure from its scope. rlhus, it may be applied to radically different kinds of distributing mechanisms, and is not to be confined to its Having thus described my invention, its

construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is, as follows:

l. In a typographical machine, the combivnation with a plurality of distributing mechanisms, of means whereby one of said mechanisms will be arrested by its abnormal operation while another distributing mechanism continues in operation.

2. In a typographical machine, the combination of a plurality of distributing mechanisms, common operating means connected separate driving connections therefor, one Y of said connections comprising a clutch by which it may be broken while the other distributing mechanism continues rin operation, together with means controlled `by the abnormal operation of one of the distributing mechanisms for opening the clutch.

5. In a typographical machine, the combinatio-n of two distributing mechanisms and separate stop devices therefor, one of said devices being adapted to act independently of the other and controlled in its action by the abnormal operation of the corresponding distributing mechanism. v

6. In a typographical machine, the combi-- nation' with a main distributing mechanism and a font selecting device, of means whereby said font selecting device will be arrested by its abnormal operation independently of the main distributing mechanism and while the latter continues in operation.V

7 In a typographical machine, the combination with a plurality of distributing mechanisms, of means whereby one of sai-d mechanisms will be arrested independently by its abnormal operation, and whereby all of said mechanisms may be arrested conjointly by the abnormal operation of another one of them.

8. In a typographical machine, the combination with a main distributingmechanism and a font selecting device each adapted to be arrested by its abnormal operation, of

means whereby the arrest of the main distributing mechanism Will effect the arrest of the font selecting device, and whereby the arrest of the font selecting device will not effect the arrest of the main distributing mechanism.

9. In a typographical machine, the combination with a plurality of distributing mech# anisms, driving mechanism therefor, automatic means for arresting one of said distributing mechanisms by its abnormal operation While another distributing mechanism continues in operation.

10. In a typographical machine, the combination with a plurality of distributing mechanisms, driving mechanism therefor, independent connections between said distributing mechanisms and said driving mechanism, and means for disconnecting one of said distributing mechanisms While another distributing mechanism remains in running connection with said driving mechanism.

In testimony whereof I affix my signature in presence of two Witnesses.
